Tribological, biocompatibility, and antibiofilm properties of tungsten-germanium coating using magnetron sputtering.

In this study, borosilicate glass and 316 L stainless steel were coated with germanium (Ge) and tungsten (W) metals using the Magnetron Sputtering System. Surface structural, mechanical, and tribological properties of uncoated and coated samples were examined using SEM, X-ray diffraction (XRD), energy-dispersive spectroscopy, and tribometer. The XRD results showed that WGe chemical compound observed in (110) crystalline phase and exhibited a dense structure.
